Which brightening skincare product has actually worked for you??

I have used multiple brightening product and i dont think any of them have ever worked for me. I am very tanned due being active in outdoor games like swimming and basketball. I do use sunscreen but they usually just melt away after 1-2hrs. And no I'm not delulu ik for a fact tht im way lighter than I am currently because back in 10th grade I didnt leave my room at all for 2 months because of boards and my skin colour had become lighter than usual. Also in those 2 months i used to take some sort of zinc supplements my dermat gave me and it can be tht they were the reason why my tan and dullness faded. But the melanin rushed back the moment 11th started.

Now that im gonna move to college next month I just want my natural skin colour back. [NO HATE TO PEOPLE WITH DARKER SKIN TONE]

For context i use Neutrogena Dry Touch Sunblock Sunscreen and the dot n key vit c sunscreen. Also i have tried good vibes vit c and b3 serum, good vibes vit c serum, plum 10% niacinamide serum, plum vit c serum, plum alpha alpha arbutin serum and the minimalist vit c serum as well.

I think minimalist did work slightly but the rest did not work at all for me.
